As I mentioned on a previous thread 4 out of five of my bitches started off with shirt intervalks between seasons fradually getting longer between, so that by the fourth or fifth season they were going 6-7 months.
My 15 month old is a week into her third season. the first two were 16 weeks apart and this one is 21 weeks since the last one started. Her Mum wnet 18 weeks then 21 and then 27 weeks. My oldest bitch had a season at 6. 9 and 12 months, and then wenbt five monts and then over six. None of them developed any problems with this and they have alll had puppoes except of course the youngest.
